Cephennium espunae nov.sp. ( Figs 9 , 22 , 49 , Map 1 )

Type material: Holotype ♂: "E - Murcia [13], Sierra de Espuña , Prado Mayor , pasture, 1140 m, 37°53'11N, 01°33'53W, 29.III.2007, V. Assing / Holotypus ♂ Cephennium espunae sp. n. det. V. Assing 2020" ( cAss).

Etymology: The specific epithet is the genitive of Espuña, the name of the mountain where the species was discovered and where it may be endemic.

Description: Body length 1.0 mm. Habitus as in Fig. 9 . Eye rudiments composed of two (?) ommatidia without pigmentation. External and male secondary sexual characters as in C. filabresicum , distinguished only by the male primary sexual characters.

♂: aedeagus ( Fig. 49 ) broad, 0.24 mm long; ventral process apically membranous and of quadrangular shape; internal structures small and weakly sclerotized; parameres fine and relatively short, not reaching apex of median lobe, and apically with a moderately short seta.

Comparative notes: Cephennium espunae is distinguished from the externally practically identical and geographically close C. filabresicum by a much smaller and differently shaped aedeagus.

Distribution and natural history: The type locality ( Fig. 22 ) is situated in Sierra de Espuña, Murcia, South Spain ( Map 1 ). The holotype was sifted from grass roots and moss in a calcareous stony grassland at an altitude of 1140 m.
